⚠️

This is the documentation for the old GraphQL Yoga version 3. We recommend upgrading to the latest GraphQL Yoga version 5.

Migrate to GraphQL Yoga v5

Parsing and Validation Caching

By default, Yoga will maintain a parsing and validation cache. If requests contain documents that have been executed before, they will not be parsed and validated again.

Using the parser cache can improve performance up to ~60%, and using the validation cache up to ~50% (based on benchmarks).

This behavior is built-in and can be optionally disabled using the parserCache and validationCache options:

Disable validation and parser caching

import { createYoga } from 'graphql-yoga'
import { createServer } from 'node:http'
import { schema } from './my-schema'
 
const yoga = createYoga({
  schema,
  parserCache: false, // disable parse caching
  validationCache: false // disable validation caching
})
 
const server = createServer(yoga)
server.listen(4000, () => {
  console.info('Server is running on http://localhost:4000/graphql')
})

Furthermore, you can provide your own cache store to both of these plugins by implementing the following interface:

Custom cache store

import { DocumentNode, GraphQLError } from 'graphql'
import { createYoga } from 'graphql-yoga'
import { createServer } from 'node:http'
import { schema } from './my-schema'
import {
  documentCacheStore,
  errorCacheStore,
  validationCacheStore
} from './my-cache'
 
interface CacheStore<T> {
  get(key: string): T | undefined
  set(key: string, value: T): void
}
 
const yoga = createYoga({
  schema,
  parserCache: {
    documentCache: documentCacheStore as CacheStore<DocumentNode>,
    errorCache: errorCacheStore as CacheStore<Error>
  },
  validationCache: validationCacheStore as CacheStore<readonly GraphQLError[]>
})
 
const server = createServer(yoga)
server.listen(4000, () => {
  console.info('Server is running on http://localhost:4000/graphql')
})

Yoga uses envelop’s plugins useParserCache and useValidationCache underneath, read more about them on their respective websites.
